I have done this repair!!
My close friend has an AmanaTag of this design that had the same problem... This is what is happening.. There are 3 pads mounted to the baseplate of the machine. These are used for the brake after spin and to hold the tub in place while agitating.. What happened in his case is that he overloaded it so much that one of each of the two sets of screws holding the pads stripped..To do this repair you need a lot of patience and dexterity.. a new set of pads and screws is around $20 from a repair shop.. First off, unscrew and remove the bottom panel. after that is done, locate all of the screws holding the cabinet to the base and remove them.. once you have the cabinet at least partially removed, locate the fill flume and remove the hose attached at the back, next, remove the pressure dome on the left side of the tub. once all that is done and you have the cabinet off, you need to remove both hoses from the pump in order to be able to get to the right side brake pad...locate all of the screws and remove all three of the old brake pads.. Then just put the new ones on, screw them in tight and put the washer back together.. I do remember telling my friend that this was a one time repair.. If it happened again that I wasn't going to repair it again and that he should go buy a new set.. This wasn't a fun repair LOL.. Good luck with whatever you choose to do...
